I bought a second-hand Garmin device (Forerunner 735XT) and tried the 'clear user data' function when this arrived but did not do a full reset (my mistake at the time). However, the activities/badges from the previous owner of the device are still connected to my account so I'm not sure if this worked.
I have connected the device to my Garmin account and begun to use the watch but now wanted to check about data security. Could the device still be linked to the previous user's account, or can it only be connected to one account at a time? Is there any way to check this/disconnect the device from my end?
If possible I don't really want to lose my data that I've saved since I got the watch by doing a factory reset. Are my activities linked to my account or the device? It seems like the activities must be linked to the device, since my account now contains all of the previous user's activities. Therefore, if they are also able to see all my activities with GPS then I would obviously want to reset anyway if needed.
All very confusing, any explanation of how it works would be appreciated!!
